Example Docker Compose Configuration

The following is a basic example configuration for using The Drum PHP Docker images alongside Xdebug.

It uses Compose's environment variable substitution to specify configuration which changes on a per-machine basis.

.env

Create a .env file specifying the remote host to which Xdebug will connect; ifconfig | grep eth0 -A 1 | grep inet | cut -d":" -f2 | cut -d" " -f1 should give you the necessary IP address.

XDEBUG_REMOTE_HOST=172.16.0.123
